Predator and CL could not provide any possible suspects.

Using Code Search for the file, "local_frame_view.h" suspecting the below Cl might have caused this issue

Suspect CL: https://chromium.googlesource.com/chromium/src/+/cf91f7965c29e2bc93e81f79cef5d77481b00e6e%5E%21/third_party/WebKit/Source/core/frame/LocalFrameView.h

szager@ -- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!
